In some conditions, when the partition confd initiates a failover to the other controller, it fails to complete the failover in a timely fashion and the original instance reclaims the active role. If the failover was due to a controller fault and is still present, it will immediately fail over again.
While the partition instance is failing back and forth, the control-plane functions are unavailable or degraded, and this can impact dataplane operations.
If a controller health fault is present on system controller-1, and the partition redundancy mode is set to either "auto" or "prefer-1".
Set the partition "system redundancy config mode" to "active-controller". When a controller fault exists, and the controller fails over, the partition will automatically prefer to follow the active controller location.
